Location: 5/5, few minutes from BTS / MRT / train, quite street with no traffic, just a minute of walk to amazing Chinatown where is tons of things to do, shop, and eat.
Hospitality: 5/5, they helped us carry the heavy luggage up and down to the top floor which was amazing since we were super tired. When we were leaving they served us free ice milk tea. :)
Room: 5/5, the room we took is the only room on the top floor, so it felt like we have our own app. The room has a great style, and altogether looks like a room from much higher price range. The bed is spacious. There is water heater for noodles, fridge, free soap, tea, etc.
We didn't have any problems with the floor cracking (we didn't notice it at all), but it is a bit slippery so it is best to wear the slippers you will get from the hostel staff.
Fast internet, small shop inside of the hostel, clean, towels, etc.
Best hostel we visited during our trip in Thailand!
